Ducted firearm suppressor

ABSTRACT

A suppressor is provided to reduce the sound produced by a firearm. The Suppressor comprises a body with a muzzle attachment facility and the body defines a linear bullet passage with a bullet exit aperture. Further, the body of the suppressor defines an articulated gas path away from the bullet passage, and the gas path has a plurality of overlaying forward flow segments and rearward flow segments and an exit aperture away from the bullet exit aperture.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent Application No. 62/633,640 filed on Feb. 22, 2018, entitled “Ducted Firearm Suppressor”, which is hereby incorporated by reference in its entirety for all that is taught and disclosed therein.

FIELD OF THE INVENTION

The present invention relates to a ducted firearm suppressor, and more particularly, to a suppressor that contains blast diversion features and reduces the sound produced by a firearm.

BACKGROUND OF THE INVENTION

Recent advancements in manufacturing technologies have expanded the design space of engineers. The ducted firearm suppressor described in this application relies on these new manufacturing technologies to be produced.

The limitations of the prior art are addressed by providing a suppressor to reduce the sound produced by a firearm. The Suppressor comprises a body with a muzzle attachment facility and the body defines a linear bullet passage with a bullet exit aperture. Further, the body of the suppressor defines an articulated gas path away from the bullet passage, and the gas path has a plurality of overlaying forward flow segments and rearward flow segments and an exit aperture away from the bullet exit aperture.

SUMMARY OF THE INVENTION

The present invention is intended to reduce the sound produced by a firearm as the blast exits the muzzle of the barrel.

The present invention consists of a body that contains blast diversion features and ducting that allow the blast pressure to dissipate over a longer period of time, cool to some extent, and exit through different openings than the projectile exit port.

The present invention and its manufacturing method allow for more compact applications as it reduces the overall length extension from the end of the barrel.

The present invention routes the blast gases via ducting under or around the barrel and allows the gases to flow freely as opposed to the traditional methods of containing the blast gases with various baffle designs.

The body of the present invention also has features to allow mounting to a firearm muzzle and can be configured to various mounting methods.
